Technical Data Sheet

Silicon Powder Description

Silicon is a metalloid and carries the typical properties of both metals and nonmetals. It is extremely inert and insoluble in water and acids. However, it can be dissolved into silicates by hot alkaline lyes. Pure silicon forms dark gray, metallic, shiny crystals. Silicon also has excellent thermal conductivity, which – in pure silicon – is accompanied by extremely low electrical conductivity. Our silicon powder is produced using minimally sized grains and is useful in applications requiring high surface areas such as water treatment, fuel cell, and solar applications.

Silicon Powder Applications

Used in semiconductor technology.
High-purity silicon (> 99.99 percent) is used for computer microchips, transistors and solar cells.
Applied as a raw material in the manufacture of reaction-bonded silicon nitride (RBSN) and for the metal infiltration of high-purity silicon carbide (SiSiC)

Silicon Powder Applications

Silicon powder is sometimes used as an anode material or an additive in lithium-ion batteries to improve performance, specifically to increase energy density and extend battery life.
Crystalline silicon can be used in the production of LEDs and other optoelectronic devices. Silicon powder is used to create materials that allow for efficient light emission.
Silicon is also used in optical coatings and films that are applied to lenses and other optical components to enhance light transmission and reflection properties.
